The energy captured in photosynthesis is used to power cellular respiration.
The energy transformed in cellular respiration is used to power photosynthesis.
Photosynthesis and respiration perform the same task in terms of energy transformation.
Energy is not involved in either photosynthesis or cellular respiration

Answer 1

The correct answer is: The energy captured in photosynthesis is used to power cellular respiration.

In photosynthesis, plants convert solar energy into chemical energy stored in glucose. Then, during cellular respiration, both plants and animals convert that stored energy in glucose into ATP, which can be used for various cellular functions. This creates a cycle where the energy captured by photosynthesis enables cellular respiration to occur.
